Estimate your ADU cost
A 2026 Orange County range by type, size, and finish. Educational estimate — for a precise number on your lot, run the full ADU Cost Calculator.
Estimated cost
$285,000 – $315,000+
Ranges cover design, engineering, the permit process, and construction under one roof, for standard Orange County site conditions. City permit, plan-check and inspection fees are paid by the owner to the city and are not in these ranges, and neither are finish materials, landscaping or solar. Sloped lots, long utility runs, panel upgrades, and coastal or fire overlays can move the number. It is an educational estimate, not a quote or a promise.
